Re-secure the housing.

3. Clean Throttle Body

Remove the intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle body, ensuring no residue remains.
Reattach the intake duct securely.

4. Inspect and Replace Fuel Filter (if applicable)

Locate the fuel filter; it may be integrated with the fuel pump in some models.
Depressurize the fuel system by removing the fuel pump fuse and running the engine until it stalls.
Disconnect the fuel lines and remove the old fuel filter.
Install the new fuel filter, ensuring all connections are tight.

5. Replace Spark Plugs and Ignition Coils (if necessary)

Remove the ignition coil covers (if applicable).
Disconnect the electrical connectors from the ignition coils.
Remove the ignition coils and spark plugs using the appropriate socket.
